SPECIFIC-*GRAVITY APPARATUS.

. Application flied an 21;

To all whom it may concern Be it known that l, J AMES J. GANUCHEAU, a citizen'of the United States, residing at New Orleans, in the State of Louisiana, ave invented certain new and useful Improvements in Specific- Gravity Apparatus, of which the following is a specification.

This invention has reference to specific gravity apparatus for recording variations in specific ravity of liquids capable of flowing throug a pipe or tube whereby there is a change in weight of the coil of the pipe on the scale platform and the changes in Weight will be recorded on a scale. The apparatus is attached to a bypass in .the supply line or the total product may be passed through the coil of the apparatus.

The invention is capable of operatin in different weights, as for instance, liqui s or materials capable of going through a tube will enter an inlet and pass through acoil suspended at a point through flexible couplings so that an variation in weightof material passing t rough the coil will actuate the arm to indicate variations in the specific gravity on a graduated scale. Such a device shows at any instance the specific gravity of any liquid or material passing through the coil.

As a variation the li uids or materials capable of goin throng a' tube may enter through an in at and ass through a susexible couplings so that any variation and wei htof material passing through the coil wil actuate an in-- dicating arm and record variations and specific gravity on a recording drum, thus makllth ing a permanent record of this specific gravity of materials continuously through the coil. A true specific gravity "varies with temperature a T recordin thermometer is placed adjacent to the in ct and the temperature of materials as they ass through the coil is permanently reoordc and corrections,

for true ecific gravity made.

As a sti 1 further variance the principles of oration are the same as those first outline but may be adapted'to change quantities of material, such, for instance, as the total output of a factor 1 The invention will a best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming part of this specification with t e understanding,

parish of Orleans and -18 connected b to a supply 0 liquid to be tested and the 1923. Serial No. 640,389.

however, that the invention is not confined to any strict conformity with the showing in the drawings but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended'claim.

In the drawings:

Figure 1 is an elevation of an apparatus through which the substance to be tested for specific gravity asses; a

Figure 2 is a p an view of a different form of the apparatus than shown in Figure 1;

Figure 3 is an elevation of still another Figure 4 is an elevation of a recorder and temperature indicator adapted for a like purpose.

Referring to the drawings, there is shown in Figure 1 a coil 1 having terminal connections 2 at opposite ends and there suspendedby a connection 12.to opposite c011 plings 4: supported by a post 5 and a base 6. The coill is suspended by a link 7 to an arm S-carried by a pivot support 9 carried by the column 5. The pivot 9 supports a pointer 10 movable overa scale 11 carried by the base 6. Asthe liquid to be tested for specific gravity passes through the coil 1, its specific gravity acts ppon the ointer 10 and is indicated on the scale 11, fiexible connections 12 connecting the coil 1 with the inlet and outranged to show upon a scale dial 16 a specific gravity indication of the liquid flowing through thecoil 13. 4

In Figure. 3 there is provided a platform scale 17 carrying upon the platform a coil flexible ball connections 19 scales are provided with a post 20 having a visible scale 21 by means of which the specific gravity is indicated. a

In Figure 4: there is shown a recorder 22 graduated to indicate s ecific gravity and having an arm 23 carrie by pivot points 24: and suspending a coil 25 through which the material being recorded is; passed, the liquid being treated flowing through pipes 26 and 27 from a supply of liquid, an adjustable weight 28 being arranged upon the arm 23 l to provide for calibration of the instrument.

Flexible couplings 30 provide for compensation of the parts to permit the movement of the recording arm 23 as necessary.

The apparatus herein described constitutes a continuous specific gravityapparatus havingthe possibilities of determining specific gravity of light or heavy liquids, mag

mas and homogeneous mixtures of any substance capable of passing through a pipe or tube. VViththe apparatus described the exact specificgravity is shown at all times ,whether it be in small quantities for test purposes or a total plant production, it be ing only necessary to furnish an apparatus I of different sizes to answer the specific requirements.

To determine the Specific gravities of magmas or homogeneous mixtures it is necessary'to fill and weigh a container for each specific gravity desired, the operations necessary to secure the desired specific gravity with mixtures would be like that explained in'handling liquids. In a homogeneous mixture beaten with air the specific gravity varies with the amount of air present as supplied by a valve which is opened and closed according to the consistency required. This requires a separate test for each amount of air appliedto the mixture. With this apparatus it is only necessary to determine the gravity desired-and the apparatus will continuouslyshow any variations above or below that desired.

5 The principle on which this apparatus works is that the volume in the pipe or tube is constant at constant temperatures so' that different gravity substance oing through the pipe will change the weig it in the coil pipe on the scale platform. The coil pipe or tube on the scale platform is connected to the supply line by flexible couplings 01' connections so that any difference in weight will be recorded on the scales. This apparatus would be attached to a bypass in the supply line or the total product may pass through the coil of the apparatus.

Another feature of this apparatus is the elimination of evaporation of light volatile liquids or mixtures of light and heavy liquids, ,the more volatile liquids evaporating when the present method of determining specific gravity is used.

' What is claimed is:
